Hadoop3.1.2 + Hbase2.2.0 设置lzo压缩算法

SassoonKennedy 发布于10月前

Hadoop3.1.2 + Hbase2.2.0 设置lzo压缩算法:

写在前面,在配置hbase使用lzo算法时,在网上搜了很多文章,一般都是比较老的文章,一是版本低,二是一般都是使用hadoop-gpl-compression,hadoop-gpl-compression是一个比较老的依赖包,现已被hadoop-lzo替代,希望遇到hadoop和hbase配置lzo算法时,能有所帮助

安装lzo库

1.下载最新的lzo库,下载地址: http://www.oberhumer.com/opensource/lzo/download/

2.解压lzo库

tar -zxvf lzo-2.10.tar.gz

3.进入解压后的lzo目录,执行./configure  --enable-shared

cd lzo-2.10
./configure  --enable-shared -prefix=/usr/local/hadoop/lzo

4.执行make进行编译,编译完成后,执行make install进行安装

make && make install

如果没有安装lzo库,在hbase中创建表时指定compression为lzo时会报错:

ERROR: org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.RuntimeException: native-lzo library not available Set hbase.table.sanity.checks to false at conf or table descriptor if you want to bypass sanity checks
	at org.apache.hadoop.hbase.master.HMaster.warnOrThrowExceptionForFailure(HMaster.java:2314)

5,库文件被默认安装到了/usr/local/lib,将/usr/local/lib拷贝到/usr/lib下,或者在/usr/lib下建立软连接

cd /usr/lib
ln -s /usr/local/lib/* .

6.安装lzop  wget http://www.lzop.org/download/lzop-1.04.tar.gz

tar -zxvf lzop-1.04.tar.gz 
./configure -enable-shared -prefix=/usr/local/hadoop/lzop
make && make install

7.把lzop复制到/usr/bin/或建立软连接

ln -s /usr/local/hadoop/lzop/bin/lzop /usr/bin/lzop

二、安装hadoop-lzo

1.下载hadoop-lzo ,下载地址:wget https://github.com/twitter/hadoop-lzo/archive/master.zip 这是一个zip压缩包,如果想使用git下载,可以使用该链接: https://github.com/twitter/hadoop-lzo

2.编译hadoop-lzo源码,在编译之前如果没有安装maven需要配置maven环境,解压缩master.zip,为:hadoop-lzo-master,进入hadoop-lzo-master中,修改pom.xml中hadoop版本配置,进行maven编译

unzip master.zip
cd hadoop-lzo-master
vim pom.xml
修改hadoop.current.version为自己对应的hadoop版本,我这里是3.1.2
<properties> 
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
  <hadoop.current.version>3.1.2</hadoop.current.version> 
  <hadoop.old.version>1.0.4</hadoop.old.version> 
</properties>

3.在hadoop-lzo-master目录中执行一下命令编译hadoop-lzo:

export CFLAGS=-m64
export CXXFLAGS=-m64
export C_INCLUDE_PATH=/usr/local/hadoop/lzo/include   #对应lzo安装的目录
export LIBRARY_PATH=/usr/local/hadoop/lzo/lib      #对应lzo安装的目录
mvn clean package -Dmaven.test.skip=true

4.打包完成后,进入target/native/Linux-amd64-64,将libgplcompression*复制到hadoop的native中,将hadoop-lzo.xxx.jar 复制到每台hadoop的common包里

cd target/native/Linux-amd64-64
tar -cBf - -C lib . | tar -xBvf - -C ~
cp ~/libgplcompression* $HADOOP_HOME/lib/native/
cp target/hadoop-lzo-0.4.18-SNAPSHOT.jar $HADOOP_HOME/share/hadoop/common/
libgplcompression*文件:

Hadoop3.1.2 + Hbase2.2.0 设置lzo压缩算法

其中libgplcompression .so和libgplcompression .so .0是链接文件,指向libgplcompression .so .0 .0 .0,

将上面生成的libgplcompression*和target/hadoop-lzo-xxx -SNAPSHOT .jar同步到集群中的所有机器对应的目录( $HADOOP_HOME/lib/native/,$HADOOP_HOME/share/hadoop/common/ )。

配置hadoop环境变量

1.在$HADOOP_HOME/etc/hadoop/hadoop-env.sh文件中配置:

export LD_LIBRARY_PATH=/usr/local/lib/lzo/lib
# Extra Java CLASSPATH elements.  Optional.
export HADOOP_CLASSPATH="<extra_entries>:$HADOOP_CLASSPATH:${HADOOP_HOME}/share/hadoop/common"
export JAVA_LIBRARY_PATH=$JAVA_LIBRARY_PATH:$HADOOP_HOME/lib/native

2.在$HADOOP_HOME/etc/hadoop/core-site.xml加上如下配置:

<property>
    <name>io.compression.codecs</name>
    <value>org.apache.hadoop.io.compress.GzipCodec,
           org.apache.hadoop.io.compress.DefaultCodec,
           com.hadoop.compression.lzo.LzoCodec,
           com.hadoop.compression.lzo.LzopCodec,
           org.apache.hadoop.io.compress.BZip2Codec
        </value>
</property>

<property>
    <name>io.compression.codec.lzo.class</name>
    <value>com.hadoop.compression.lzo.LzoCodec</value>
</property>

如果没有配置,在hbase中创建表时compression指定lzo时会报错:

Caused by: org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.hadoop.compression.lzo.LzoCodec
	at org.apache.hadoop.hbase.util.CompressionTest.testCompression(CompressionTest.java:103)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	at org.apache.hadoop.hbase.io.compress.Compression$Algorithm$1.buildCodec(Compression.java:124)
	... 13 more

3.在$HADOOP_HOME/etc/hadoop/mapred-site.xml加上如下配置:

<property>
    <name>mapred.compress.map.output</name>
    <value>true</value>
</property>

<property>
    <name>mapred.map.output.compression.codec</name>
    <value>com.hadoop.compression.lzo.LzoCodec</value>
</property>

<property>
    <name>mapred.child.env</name>
    <value>LD_LIBRARY_PATH=/usr/local/hadoop/lzo/lib</value>
</property>

<property>
    <name>mapreduce.reduce.env</name>
    <value>LD_LIBRARY_PATH=/usr/local/hadoop/lzo/lib</value>
</property>

<property>
    <name>mapred.child.env</name>
    <value>LD_LIBRARY_PATH=/usr/local/hadoop/lzo/lib</value>
</property>

将上述修改的配置文件全部同步到集群的所有机器上,并重启Hadoop集群,这样就可以在Hadoop中使用lzo。

在Hbase中配置lzo

1.将hadoop-lzo-xxx.jar复制到/hbase/lib中

cp target/hadoop-lzo-0.4.18-SNAPSHOT.jar $HBASE_HOME/lib

2.在hbase/lib下创建native文件夹,在/hbase/lib/native下创建Linux-amd64-64 -> /opt/hadoop/lib/native的软连接

ln -s /opt/hadoop/lib/native Linux-amd64-64

如图:

Hadoop3.1.2 + Hbase2.2.0 设置lzo压缩算法

3.在$HBASE_HOME/conf/hbase-env.sh中添加如下配置:

export HBASE_LIBRARY_PATH=$HBASE_LIBRARY_PATH:$HBASE_HOME/lib/native/Linux-amd64-64/:/usr/local/lib/

4.在$HBASE_HOME/conf/hbase-site.xml中添加如下配置:

<property>
     <name>hbase.regionserver.codecs</name>
     <value>lzo</value>
</property>

5.启动hbase一切正常

注意:关于hadoop-gpl-compression的说明:

hadoop-lzo-xxx的前身是hadoop-gpl-compression-xxx,之前是放在google code下管理,地址:http://code.google.com/p/hadoop-gpl-compression/ .但由于协议问题后来移植到github上,也就是现在的hadoop-lzo-xxx,github,链接地址: https://github.com/kevinweil/hadoop-lzo .网上介绍hadoop lzo压缩绝大部分都是基于hadoop-gpl-compression的介绍.而hadoop-gpl-compression还是09年开发的,跟现在hadoop版本已经无法再完全兼容,会发生一些问题。因此也趟了一些坑。希望能给一些朋友一点帮助。

在使用hadoop-gpl-compression-xxx.jar时,hbase启动会报如下错:

当删除hadoop-gpl-compression-xxx.jar时,替换为hadoop-lzo.xxx.jar后,再启动hbase,一切正常:
